TO DANCE WITH THE BEAST...ANOTHER SD THREAD

I've never ran a SD cycle but may want to in the future and considering recent events I may have to purchase it now if I ever want to run it. So after creepin around the old intraweb I came across all types of cycle lengths and variations. SD to Epi bridge seems to look like an interesting possibility for a future cycle. So my questions are: What is the ideal cycle length for a solo SD run? And has anyone had any success with the SD/Epi bridge?
